1964 Lotus 30

This car competed in the World Sport Car Masters race at the Silverstone Classic meeting in July 2010.

It's the 1964 Lotus 30 of Matthew Watts, and according to the programme of the event has a 5300cc engine. The Lotus 30 had a backbone chassis similar to that of the Lotus Elan instead of the space frame chassis of Colin Chapman's last sports racing car, the Lotus 19, and was intended to compete in Can AM racing. Lotus engineer and designer Len Terry refused to have anything to do with the car because he considered that the backbone chassis would not give sufficient torsional stiffness, and except for some early encouraging results at the hands of Jim Clark the car wasn't a success. The Lotus 30 was originally built with a Ford 289 cu in (4,727cc) engine.
